BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a mobile communicationterminal (or “mobile terminal”), and more particularly, to a method andsystem in which a mobile terminal connected to an arbitrary electronicdevice interacts with the arbitrary electronic device.

2. Description of the Related Art

With the general use of mobile terminals and the development of theirfunctions, applications which have been implemented in electronicdevices such as a computer, a television and a Portable MultimediaPlayer (PMP) are now available even in mobile terminals, and functionalapplications of mobile terminals can also be executed in a computer. Inaddition, there is an increase in number of applications which areexecuted through interaction between a mobile terminal and a computer.

For example, such applications may include an application fortransmitting various information stored in a computer, such as contactinformation, schedule information, photo files, music files, video filesand Internet bookmark information, to a mobile terminal, and anapplication for downloading images and the like stored in a mobileterminal into a computer. For execution of these applications, thecomputer and the mobile terminal should be connected to each other in awired or wireless manner, and synchronization may be achieved to keepthe latest information between the two devices. Also, there is anapplication for delivering digital multimedia broadcast data received ina mobile terminal to a connected television to display the receivedbroadcast data on the television.

As another example, there is an application, with which a computer sendsmessages based on Short Message Service (SMS) and Multimedia MessageService (MMS) which are functions of mobile terminals. Accordingly, auser may send SMS messages or MMS messages from a computer connected tothe Internet to mobile terminals of other users. Since the user sendsmessages based on SMS provided by a separate external service systemwithout using his/her own mobile terminal, it is common that the usershould subscribe to the SMS service before sending the messages.

MMS generally transmits data generated by and/or stored in a mobileterminal, for example, photo files created by photographing with amobile terminal. However, in some cases, a user, who is using acomputer, may send images stored in the computer to mobile terminals ofother users. In this case, as in SMS, the user uses the system aftersubscribing to the separate service system providing MMS, without usinghis/her mobile terminal. Also, the user may download desired images tothe mobile terminal and then send them using an MMS function of themobile terminal.

In order to send text to other mobile terminals, the user can use aseparate messaging service that is accessible via a computer. The useris usually required to subscribe to the separate messaging service.

If a user sends messages to other mobile terminals over his/her ownmobile terminal without using the separate messaging service accessiblevia a computer, the user directly inputs the content displayed on acomputer screen to the mobile terminal using a keypad of the terminal,causing inconvenience.

A more complex process is required when a user, who is using a computer,delivers images on some areas of a computer screen to his/her own mobileterminal, or transmits the images to other mobile terminals throughhis/her own mobile terminal.

First, an image to be transmitted among the data displayed on a computerscreen is stored in the computer as a particular image file. Thecomputer and a mobile terminal are connected in a wired or wirelessmanner, and the stored image file is downloaded to the mobile terminal.Thereafter, if it is desired to send a message by MMS, the mobileterminal executes an MMS function, attaches the downloaded image file tothe message, inputs a phone number of a receiving mobile terminal, andsends the message.

In this case, due to the complex procedure, only a person with a certainlevel of knowledge about a file download method between the computer andthe mobile terminal can store a particular image file in his/her mobileterminal.

Besides, the user needs to directly input a phone number to the mobileterminal even when dialing a phone number displayed on the computerscreen or sending an SMS message and an MMS message to the phone number.

In the above examples, the user is required to input many charactersusing a small keypad on the mobile terminal, causing inconvenience, andthere is a possibility that characters or phone numbers may be wronglyinput. In addition, the user must check both the computer screen and themobile terminal screen.

If a user wants to output an image file stored in a mobile terminalusing a printer connected to a computer, the user needs to firstdownload the image file from the mobile terminal to the computer. Thenthe user needs to run an application required to print an image file bymanipulating the computer, search for the image file, and make a requestto print the image file through the printer. That is, the user mustmanipulate both the mobile terminal and the computer in order to printimage files stored in the mobile terminal

In addition, descriptions of well-known functions andconstructions are omitted for clarity and conciseness.

According to embodiments of the present invention, in the state where aseparate electronic device and a mobile terminal are connected, a usermay operate functions of the mobile terminal by manipulating only theelectronic device without manipulating the mobile terminal, or executeoperations associated with functions of the mobile terminal in theelectronic device by manipulating only the mobile terminal.

The electronic device refers to a device that can enable dataprocessing, execute at least one application independently, and displayor store the data generated by the application execution, and theelectronic device includes a minimum user input unit. Such electronicdevices include computers, televisions, PMPs, Personal DigitalAssistants (PDA), electronic dictionaries, mobile terminals, digitalmultimedia receivers, electronic book terminals, etc.

According to the present invention, an electronic device may delivercontent and a functional application command of a mobile terminal thatwill execute the content, which are selected by a user, to the mobileterminal, and the mobile terminal may execute the functional applicationusing the provided content. If a user selects arbitrary content fromamong content displayed on and/or stored in the electronic device, andselects a functional application and its associated command of themobile terminal that will execute the content, then the electronicdevice delivers them to the mobile terminal and the mobile terminalexecutes the functional application corresponding to the command usingthe received content.

An event that has occurred in a mobile terminal may be delivered to anelectronic device connected to the mobile terminal so that a user mayrespond to the event using the electronic device. An operation for theresponse may be executed in the mobile terminal or in both the mobileterminal and the electronic device in an interactive manner.

If the user delivers a particular command to the connected electronicdevice by manipulating the mobile terminal, the electronic device mayexecute an application associated with a function of the mobile terminalaccording to the command.

An example of a system to which the present invention is applicable isshown in FIG. 1, in which a computer 100, i.e. an electronic device, isconnected to a mobile terminal 200.

The computer 100 includes an interactive service application 140, acontent extractor 130, a phone service application 120, a device agent110, a user input device (not shown), and a display device (not shown).

The user input device is a device by which a user may input data, andmay include, for example, a keyboard, a mouse, etc.

The interactive service application 140 is an application for allowingthe computer 100 and the mobile terminal 200 to execute an operationassociated with a function of the mobile terminal 200 in an interactivemanner. The interactive service application 140 sets an interactiveservice mode during its execution. In order to allow the mobile terminal200 to use content that is displayed on a screen by an arbitraryapplication being executed in the computer 100, or content such as adata file being used by a particular application, by means of multiplefunctional applications of the mobile terminal 200 connected to thecomputer 100, the interactive service application 140 provides a selectindicator for allowing a user to select content and a context menu forallowing the user to select a functional application of the mobileterminal 200. The select indicator may include, for example, a cursor, amouse pointer, a select window, and the like. The select window is anindicator for adjusting and deciding a size of an image to be capturedon a screen of the computer 100. The context menu includes a menu itemcorresponding to each of the multiple functional applications of themobile terminal 200, a menu item for data transmission/reception betweenthe computer 100 and the mobile terminal 200, and a search menu capableof searching for various data files stored in the computer 100. The menuitems may include menu items corresponding to, for example, callsending, SMS sending/receiving, MMS sending/receiving, memo writing,etc. and the various data files may include an image file, a music file,a video file, a text file, and the like. This context menu may beprovided in the form of a tool bar.

Further, the interactive service application 140 invokes the contentextractor 130 during its execution, and invokes the phone serviceapplication 120 according to a user input.

The content extractor 130 extracts data that the user selected using theselect indicator, from among data that is displayed on the screen as anarbitrary application is executed in the computer 100, and from a datafile being used in an application being executed, and delivers theextracted data to the phone service application 120 after converting theextracted data into an appropriate format.

For example, if a user selects text using a cursor or a mouse pointer inthe state where a web browser is executed and an arbitrary web page isdisplayed, the content extractor 130 extracts the selected text,configures execution data including the extracted text, and delivers theconfigured execution data to the phone service application 120. Thecontent extractor 130 may also extract text or an image from a displayedtext file in the state where a text application is executed. As anotherexample, if the user selects a music file play application using a mousepointer in the state where an arbitrary music file is being played bythe music file play application, the content extractor 130 may searchthe memory of the computer 100 for the music file being played, extractthe searched music file from the memory, and configure execution dataincluding the extracted music file.

If the content extraction is completed, the content extractor 130 mayprovide at least one functional application item of the mobile terminal200, which can use the extracted content, according to a type of theextracted content. As in the example above, if text is selected, thecontent extractor 130 determines whether the selected text is a phonenumber consisting of a number. If so, the content extractor 130 mayprovide at least one of call sending/receiving, SMS sending, and MMSsending items. If execution of a particular functional application isgranted or selected by the user, the content extractor 130 furtherincludes information about the functional application in the executiondata and delivers the execution data to the phone service application120.

Also, even if the user searches for and selects a data file stored inthe computer 100 by means of the search menu provided in the contextmenu without using the select indicator, the content extractor 130 mayprovide at least one functional application of the mobile terminal 200,which can use the selected data file.

If the user selects a particular functional application by means of thecontext menu in a state where the user has not selected any contentusing the select indicator or the search menu, the content extractor 130may configure execution data including only information about theselected functional application. Thereafter, the content extractor 130may include in the execution data content that is selected or createdaccording to a user input, for example, a select indicator, a user'sdirect input, or a search for data stored in the computer 100. Thecontent inclusion may be achieved by the content extractor 130 or thephone service application 120.

The execution data may include information about a functionalapplication to be executed in the mobile terminal 200, informationneeded for execution of the functional application, and content selectedby the user. The execution data may be configured as shown in Table 1according to an embodiment of the present invention.

With reference to FIGS. 3 and 4, a description will be made ofoperations of the computer 100 and the mobile terminal 200 according toan embodiment of the present invention in the state where the computer100 and the mobile terminal 200 are connected in a wired or wirelessmanner.

If an interactive service mode is set in the computer 100 as a user runsthe interactive service application 140, the interactive serviceapplication 140 in the computer 100 provides a select indicator. Theuser may select desired content among the data displayed on the computer100 using the select indicator. For example, in a state where a web pageis displayed as a web browser is executed, the user may select aparticular number string by dragging a number string in the web pageusing a mouse pointer in step 11. Then the content extractor 130automatically extracts the content selected by the user, i.e., thenumber string, and identifies its type in step 13. Depending on the typeof the content, the content extractor 130 provides a functionalapplication item of the mobile terminal 200 capable of using the contentin step 15. If the content is a number string as in the above example,menu items including call sending, SMS sending and MMS sending may beprovided. The user selects an application corresponding to any one ofthese menu items in step 17. In response, the content extractor 130configures execution data that corresponds to selected function andcommand and includes the extracted content in interaction with the phoneservice application 120, and delivers the execution data to the mobileterminal 200 via the device agent 110 in step 19.

Then the mobile terminal 200 receives the execution data via the phoneagent 210 in an interactive service mode in step 31. The phone agent 210identifies a functional application and a command of the mobile terminal200, which correspond to the execution data, and delivers the functionalapplication and command to the phone application 220 in step 33. Thephone application 220 executes the functional application and commandusing the content included in the execution data in step 35.

For example, upon receiving execution data in which Call Sending isdesignated and which includes a phone number, the mobile terminal 200performs a call to the phone number.

While it has been described in the above example that the user firstselects content and then selects its associated functional application,the user may first select a functional application and then selectcontent. In this case, if the user selects a particular functionalapplication by means of the tool bar 141 or the context menu 142, thecontent extractor 130 configures execution data including informationabout the particular functional application and delivers the executiondata to the phone service application 120. In response, the phoneservice application 120 provides a user interface for the functionalapplication. Thereafter, content selected or input by the user shall beincluded in the execution data.

A phone event, such as call receiving, message receiving and alarming,may occur in the mobile terminal 200. Operations of the mobile terminal200 and the computer 100 in this case are shown in FIG. 5. The phoneevent is an event that occurs in the mobile terminal 200 with respect toan operation of a functional application provided in the mobile terminal200. The phone event includes both an event occurring based on the datareceived externally, such as call receiving and message receiving, andan event occurring based on an internal operation, such as an alarm,power shortage alert and/or schedule alert.

Referring to FIG. 5, if a phone event occurs in the mobile terminal 200in step 71, the phone application 220 detects and delivers the phoneevent to the phone agent 210, and the phone agent 210 delivers the phoneevent to the device agent 110 in step 73. The device agent 110 deliversthe phone event received from the phone agent 210 to the phone serviceapplication 120, and the phone service application 120 displays thephone event by activating a functional application associated with thereceived phone event in step 75. Accordingly, the user may check thephone event and then input a response thereto to the computer 100through a user input device of the computer 100. Upon detecting theresponse in step 77, the phone service application 120 in the computer100 delivers the response to the mobile terminal 200 and executes afunctional application corresponding to the phone event in interactionwith the mobile terminal 200 in step 79.

For example, in the case of a call receiving event, if the user respondswith the computer 100, the computer 100 sends a call receive response tothe mobile terminal 200, so that a call channel is connected in themobile terminal 200. The mobile terminal 200 delivers a voice signalreceived over the call channel to the computer 100 so that the voicesignal may be output through a speaker of the computer 100. The computer100 may deliver a voice signal received through a microphone to themobile terminal 200 so that the voice signal may be delivered to theother party through the mobile terminal 200. In other words, the usermay respond to a call received at the mobile terminal 200 and talk tothe caller, using the computer 100.

While overall operations of the computer 100 and the mobile terminal 200have been described so far, specific embodiments of the presentinvention will be described with reference to FIGS. 6 to 21.

Referring to FIG. 6, in the state where the computer 100 and the mobileterminal 200 are connected in a wired or wireless manner, if aninteractive service mode is set as the interactive service application140 is executed, the device agent 110 sends a request for phone bookdata to the phone agent 210, and in response, the phone agent 210delivers a phone book and a call history to the device agent 110, sothat phone book synchronization may be achieved between the computer 100and the mobile terminal 200, in steps 301 and 303. A detailed operationregarding this is shown in FIG. 7.

Referring to FIG. 7, the connection manager 112 in the device agent 110sends a Hello command to the connection manager 211 in the phone agent210 to request connection check in step 401. Upon receiving the Hellocommand, the connection manager 211 in the phone agent 210 sends a HelloACKnowledgement (ACK) to the device agent 210 in step 403. Thereafter,the connection manager 112 in the device agent 110 sends a request for aphone book to the phone agent 210 in step 405. The phone book manager212 in the phone agent 210 delivers all address book information orphone book information in the mobile terminal 200 to the device agent110 via the connection manager 211, and the device agent 110 stores thereceived phone book information in the phone book manager 111 in step407.
